Those who have been following the story of Suman's project will remember that he previously was using the Gt37 a/k/a T67Ptrim which is similar to the turbo I use on my Dyno Flash Evo 8

Suman did not care for the laggy response between shifts and lack of power to the area of the curve and he elected to try the new Precision Turbo line up of billet wheel turbos. His selection was the PT62/62 with genuine ported compressor inlet and 63 a/r ford 5 bolt T3 turbine housing which is very similar to the so called AMS Gt850

Suman has a stock head Evo IX with valves, built bottom end , cosworth cams, AEM, Aquamist and other supporting mods including a Buschur exhuast and race fmic

Tonight with the addition of the new turbo I did some quick tuning on the dyno jet and came up with some really great results

Our previous best with the Gt37 was in the 650 range on pump gas and alcky at 37 psi

This evening we beat that with ease and have a significantly faster spooling turbo which makes a lot more area under the curve

I compared this turbo to the HTA Gt35 of the Bad Bish and found that this 62 mm wheel is able to breath a bit better up top perhaps 20 whp additional capacity but the Bad Bish was about 150 - 200 rpms faster to spool

Here is the peak pump gas and alcky dyno sheet



Note - I am now very impressed with the Indy Wilson intake maifold - it seemed to really shine on this combo

Here is an interesting comparison between the two turbos at around 33 - 34 psi



You can see that the PT62/62 is much faster to spool and has the same top end at that bost level

Here is the TQ and WHP at 33-34 psi



There are some videos comming out on the Dyno Flash You Tube channel which I can not post here due to rules regarding posting of fast driving on public roads but which many users may find entertaining

I was super impressed with this turbo and in light of the results here I think I wll try this unit on my STI which currently has the GT35 and which makes 540 whp on pump with alcky

 

awesome results...but DAMN Suman..changing MADE parts all the time. Car seems to have a huge area increase under the curve.

 

Nice work Big AL.. 6262 is one badbish.. I have it on my RS as well and the car flies.. Good luck with it Suman..

Mike

 

Yes indeed. It should be noted that the Exhuast manifold is a AWD Motorsports creation which has really performed very well over our testing.

Al

 

so this turbo has the 63 5 bolt pte housing right?

 

Correct

 

was turbo before gt37r was it 63 too?

 

Here is good data on 63pte housing, which work great and look at all the power it makes.

 

The same

 

Al,did you do any back to back test FS635 vs PT6262 ?

 

that is a great looking graph

 

did Suman sell the car?

 

"Note - I am now very impressed with the Indy Wilson intake maifold - it seemed to really shine on this combo." Big Al
Not bad for a one off v3 with a 3". I'm glad you you like it, now take it to the track. Indy

 

Great job Suman and Al I really like the manifold set up's on both sides of the head!

Make me wanna try the 635 on my car again since Buschur COP

 

When is the car going to the track? The car should be as fast or faster than the three Buschur cars with that much horsepower.
